HIRING-PER ROLL FOR CLOTHES XVRINGERS.

Application, filed May 12,

To all whom it may concern.' i

Be it known that I, GUsTAvn HjJANTZ, a citizen of the United States, residing at l/Vyoming, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvem'entsin `Wringer Rolls for Clothes llVringers, of ywhich the following is a specification.Y i

Wringer rolls as heretofore constructed comprise a central shaft towhich has been aiiixed, in suitable manner, a "cylindrical body ofresilient material, such as rubber, the rubber having in practice been laid around the Vshaft in layers, Vand -then vulcanized 'so as to fix the rubber andshaft together. VVringer rollsare usually provided with power transmitting means, for instance cog-gears, at the respective ends thereof, and with driving means, for instance a handcranlr, when the wringer is intended for manual operation, or with a suitable coggear or cog-gears when the wringer is intended for power actuation,`for instance in connection with a power washing machine.

The coating or covering of the wringer roll deteriorates in Vcourse of time, and when it has been desired vto provide a new wringing surface, it has been found neces"- sary for the user to purchase an entirely new roll, including the power impartii'igV and the power transmitting means thereon, for. the reason that, as heretofore constructed, the body of the resilient materia-l or rubber has been permanently vulcanized to the shaft. Shafts of various lengths and with various propelling means thereon have heretofore been made by the dierent manufac turers of wringers, so that it has beennee eesary heretofore for the user, if he desired to `renew hiswringer rollto obtain an entirely new wringer roll and its attendant parts., comprising driving and transmitting` means, from the 'manufacturer ofthe particular machineV which he has been using.

.it is the objectof my invention to so construct the wringer roll in novel manner that the resilient surface is provided with a foundation or slie'll,"so'that the same may be renewed without the necessityfofreriew- Ving the working parts connected therewithi further, to provide novel arrangements of shaft-sections and "drivingV "connections therefor with the foundation or shell of the wringen roll: further, to provide Tnovel driving arrangements between "the `proxiniate- 1920.

ends of the shaft-sections; and. further, to provide novel supporting means between the sections of the drivingshaft and the shell of the wringer roll. A

"The invention will be further "readily un` derstood` from the following description and claims, and from the drawings in which latter: p g g K l represents a front elevation ofan exemplified wringer, embodying my invention, and adapted; to ,be employed withA power washing machine, parts being broken away'and-parts beingshown in section for better illustration.

My `present invention is. an extension kof the invention shown, described andclaimed in my applica-tion `for patent on improvements in wringer rolls for clotheswringers, filedDecember 8.,V 1,919, Serial No $43,322.

The Vwringer frame.V is exemplified at V21, and 'may be of any suitable, usual or desired construction. A wringer roll 22 is arranged to,cooperate with a wringrf'roll 23. The

shaft of the ,wringer roll 22 is arranged to` rotate in bearings 24 in therframe, and the shaft 25 of the wringer roll 23 is arranged to have bearings 26 coact therewith. The bearings 26 are arranged to slidein guideways 27 in the frame, pressure means being provided to exert pressure thereon for causing pressure between the rolls when wringing the clothes. A spring 28 may be employed to exert this pressure, being shown adjustable by means of a screw 29, threaded in a bearing 80, on the cross-bar 31 of the frame. I have exemplified my invention as applied to the wringer roll 22 which is the driving wringer roll ofthe pair, being in practice, the lower wringer roll, but it is intended that both of the wringer-'rolls have my invention applied thereto.

Cog-gears 35 are fixed, as by pins 36, to

i' theshaft of the driving wringer roll and are arrangedto mesh with cog-gears 37 secured fxedly, as by pins 38, to the shaft of the driven wringer roll. Gear-covers 4:1, secured to the frame, may be provided for the cog-gears and extend over the ends of the resilient portions of the wringer rolls for protecting the same and the clotheswhich are being operated on.

n The shaft of the driving wringer roll is provided with suitable driving 'means These driving means may be'either power driven oi Vmanually operated. Irhave in Fig. l shown the same as power driven means, comprisinga driving bevelgear 46 which meshes with bevel-gears 47, 48', normally loose about the shaft of the driving wringer roll, Vwhich is extended for the purpose. sha-ft, hold the bevel-gears 4:7, 48, in mesh with the bevel-gear 46.V A clutch-collar 50 has spline-connection 5 1. with said shaft and is arranged tobe moved lengthwise into Y neutral position or for engagement of one of the clutches 52, 53, respectively for at-rest position of the wringer rolls, or for driving the wringer rolls in either direction.

I have in Fig. 2 exemplified the shaft of` the driving wringer roll provided with a crank-handle 56 of usual construction, secured to the shaft of the driving wringer roll by usual means, as by a screw-threaded connection 57 between the hub of' the crankhandle and said shaft, and a nut 58 received over the threaded reduced end 59 of i said shaft.

The wringer parts and the operating parts for the wringer rolls may be of usual or ordinary construction, and I have shown and described a usual form of the same as an exemplilication. Y l It has been the practice heretofore, when a wringer roll has become worn, to replace the same with a new wringer roll including the driving means thereon, as well as the "loog-gears fixed thereto, for ,the reason that Collars 45, fixed by pins 49 to the' have been built up as integral structures including the central shaft, the resilient ma terial vulcanized thereon, the cog-gears on theshaft, aswell as power driving means thereon or the securing means thereon for the crank-handle when Va crank-handle is employed, or other driving and power transmittingmeans which may be employed.

In my improved construction I mount the resilient clothes contacting portion of the wringer roll, exemplified at 66, on a releasable foundation or shell, so thatthis releasable foundation 'or Vshell with its resilient covering, may be replaced by afresh or new releasable foundation 'or .shell with its resilient covering without the necessity of re placement of the shaft, the cog-gears, or the driving or power transmitting means. emplifying such construction, I provide a shell 61, which isv shown as an integral shell,

although the saine may be'made pluri-part in any suitable manner, for instance as shown, described and claimed in my aforesaid pending application. rIhe shell is pro-V vided at each end thereof with a collar62, and at an intermediate point o-f its interior with a collar 63, these collars being preferably inalinement.

I prefer to provide a shaft comprisingl a plurality of shaft-sections, exemplied at 65. 66. The respective shaft-sections Vare provided with the driving means or power transmitting means, such as may be employed, for instancewith the cog-gears 35v fixed thereto, one of the shaft-sections being also provided with the driving means, when the driving means are employed on the shaft. Y

The respective shaft-sections are preferably received into the shell through oppo site ends of the latter, and. theproximateV ends of the shaft-sections are'provided with coacting parts to cause driving relation between the shaft-sections, these driving rela@ tions being preferably located within or adjacent to the inner collar in the shell, in order that the inner collar may aid inthe correct positioning of the proximate ends of the shaft-sections, the proper locking relation of the proximate ends of the shaft-sections and in the proper maintenance of axial relation between the shaft-sections and the shell. Y Y Y 4 The Vdriving connections between the shaft-sections preferably include overlap-V ping proximate ends of the Vshaft-sections. Thus in Figsj to 6 inclusive, I have shown the inner proximate ends of the shaft-sec! tions provided with interengaging tongues- 71', 72, the tongues 72'forminga groove 7 3 collars. p axial relation between the inner or proxi- `outer ends of the shaft-sections, all the collars actingto maintain the shaft-sectionsin alinement.

The construction yis preferably suoli that roundshaftfsections may be employed, the walls-of the collars being preferably round to correspond with the cross-sectional forni of the shaft-sections. Pins may be received through the ends of the shell and the respective shaftsections for securing the shaft-sections and the shell together, these pins being :preferably taper pins, which may be readily driven out in usual manner for releasing the shaft'sections from the shell.

lCircum'ferential spaces 77 are preferably located circumferentially `between the shaftsections and the shell, lengthwise of the shaft-sections, between the collars in the shell. The Yshaft-sectionsV `therefore `prefer- ;a-bly'malre Vcontact with the shellonly at the The interior collar maintains the mate ends of the shaft-sections and maintains the shaft-sections in axial alinement, and, furthermore, prevents llateral displacew ment between the proximate ends of the shaft-sections in order to maintain the locling relation between them. v

Other forms of connections "betweenfthe inner ends of the shaft-sections may be einployed. 'I have shown a modification in Figs. 7 and 8, in which each of the shaft-- sections has one of its sides removed lengthwise thereof, for forming rabbets 8l, and tongues 82 received in the. rabbets, and forming proximate faces 83 on said tongues extending lengthwise of the tongues and shaft sections, to form driving relation between the shaft-sections in conjunction with the inner wall of the inner collar.

A further modification Yis shown in Figs. 9.and 10, in which the inner end of one 0f the shaft-sections is provided with a-tongue 85, exemplified as polygonalin cross-section, received in a corresponding and coacting socket 86, in the inner end of the other shaftlsection. The proximate ends ofthe shaft-sections are further supported `by the inner collar in the shell.

The shell is preferably made of metal, forming a foundation for the resilient body 60 ofthe shell, preferably vulcanized thereonin any ordinary or usualmanner.

The .shaft-sections are preferably inserted into the shell after completion of the releasable wringer-roll thus formed, the inner ends ofthe shaft-sections being placed in coactive relations and positioned in lateral directions by the inner collar. "The ends of the inner collar aretapered inwardly, as shown at 87, and the inner ends of theshaftsections are tapered, as shown at 88, 89,-in Figs. 3 and l, at 91, 92, in Figs. 7 and 8, and at 93, 94, `95., in Figs. 9 and 1G, to permit ready assembling of the parts. The pins 75 may then be inserted for connecting the shell and the sl aft-sections togetheinand for aiding and rotatively securing the shaft# sections and the reieasable wringer roll together, and lining the shaft-sections endwise with relation to the wringer roll, when the shaftseetions are in place. The aires of rotation of the shaft-sections and of the shell are coincident.

When ft is desired to renew the releesable wringer roll in my improved device, the pins 75 are removed and the shaft-sections are withdrawn endwise out of the shell, a new releasable wringer roll beingsubstituted for the worn releasable wringer roll. The shaftsections and new releasable. wringer roll are assembled in the manner hereinbefore described.

in order to facilitate release between the shaft-sections and the shell, the shaft-sections have their proximate ends so disposed that one Aof the shaft-sections may be employed to drive the other of the shaft-sections endwise to release its connection with its bearings for ready removal of the same. The provision of the circumferential spaces about the shaft-sections between the bearings in the shell reducethe danger of the shaft-sections becoming fixed, as by rust, in the shell.

My improved construction further provides extreme strength in the middle of the roll, where the greatest pressures on rolls of this character are directed, for the reason that the inner collar forms strengthening` means or strengthening rib for the shell and (acts further to strengthen the shaft and maintain the shaft-sections in coincident axial alinement. rllhe provision of the spaces 'between the bearings prevents the rusting in of the shaft-sections.

l have in Figs. ll and l2 shown a form of my invent-ion embracing the shell provided with a resilient covering, the shell being provided with the end-collars and the intermediate collar hereinbefore described, and with the intermediate circumferential spaces therebetween, an integral shaft 97, provided with the driving means and inotion transmitting means, being received through the shell" and through said collars.,-

and having support in each of said collars, and spaced from the inner wall ofthe shell between the collars for ready Vendwise removal of the shaft, in case this might be desired. The ends of the shell are secured to the shaft by means of taper pins 98, and 'he cog-gears 35 are secured to the shaft by taper pins 99. rlie pins may be readily removed, if it is desired to renewA the releasable wringer roll.

Having thus fully described my invention, what l claim as new, and desire to secure by Letters Patent, is:
